I bought an older home that came complete with an giant, ancient furnace. I had many contractors come and bid on a replacement furnace and a/c install. Of all the contractors I called, PPM was the ONLY one that gave me options for high efficiency. They were the ONLY ones that cared to tell me about higher electric costs with certain units, they were the only ones that even bothered to explain different types of systems to me, and they were the ONLY ones who instantly recognized the old furnace in my house and knew how to remove it without taking walls down like all the contractors mentioned doing. Because of PPM, I ended up getting something completely different from what I originally wanted, because I hadn't known there was a difference.
Pros: Extremely efficient. They know their stuff!
